Abstract

Cette invention concerne un procédé de sélection de canal pour une télévision réseau interactive, lequel procédé consiste à afficher simultanément des images de chaque canal dans un ensemble de canaux sur un écran en fonction du flux multimedia reçu; les images de chaque canal dans l'ensemble de canaux sont respectivement présentées dans différentes zones de l'écran sous la forme d'onglets; à recevoir un signal envoyé par un dispositif de commande; si le signal est un signal de commutation de page, à commuter l'ensemble de canaux; si le signal est un signal permettant de sélectionner une image particulière dans l'ensemble de canaux, à commuter vers le canal représenté par l'image particulière. Cette invention concerne également un procédé de codage, un dispositif de codage composite et un boîtier décodeur pour la télévision réseau interactive. Le mode de réalisation susmentionné permet de résoudre le problème lié à la lenteur de la commutation des canaux dans l'art antérieur.
